Microsoft has been busy preparing their next release of Windows Phone 7, codenamed "Mango." The update is available to developers in beta form now, and is part of a massive overhaul to the platform. As part of that upgrade Microsoft today overhauled their developer website, the App Hub.

According to WPCentral, the App Hub went down for scheduled maintenance and has now been made live again with new features. These include:

Updated layout

New crash reports

Export of download/purchase details

Private beta Marketplace

The new features are being praised by developers as more useful already, and Ivan Zivkovic sent us over a picture showing the download/crash counters in action, as shown below.

The private beta marketplace allows developers to run beta programs via the marketplace, so that rather than sideloading the XAP file a URL can be provided to other users and the developer can push updates to the beta software via the marketplace rather than sending out new XAP files to be sideloaded every time.

It's good to see the features trickling out slowly. These specific features work specifically with Windows Phone 7 OS "Mango" which is expected release to carriers in September. Mango brings over 500 new features to the platform, including IE9 with HTML5 support, mulititasking, OS-wide IM integration and more.
